From: Wei Yang <richard.weiyang@xxxxxxxxx> Subject: mm/slub.c: remove a redundant assignment in ___slab_alloc() When the code comes to this point, there are two cases: 1. cpu_slab is deactivated 2. cpu_slab is empty In both cased, cpu_slab->freelist is NULL at this moment. This patch removes the redundant assignment of cpu_slab->freelist.
